Opalotype or opaltype is an early technique of photography. Opalotypes were printed on sheets of opaque, translucent white glass; early opalotypes were sometimes hand-tinted with colors to enhance their effect. The effect of opalotype has been compared "to watercolor or even pastel in its softer coloring and tender mood.Opalotype portraits…for beauty and delicacy of detail, are equal to ivory miniaturesThe basic opalotype technique, involving wet collodion and silver gelatin, was patented in 1857 by Glover and Bold of Liverpool. Opalotypes exploited two basic techniques, using either the transfer of a carbon print onto glass, or the exposure of light-sensitive emulsion on the glass surface to the negative. Opalotype photography, never common, was practiced in various forms until it waned and disappeared in the 1930s. “Milk glass positive” is another alternative term for an opalotype.
Opalotype is one of a number of early photographic techniques now generally consigned to historical status, including ambrotype, autochrome, cyanotype, daguerrotype, ivorytype, kallitype, orotone, and tintype.
